Cursor allows writing in-workspace files with no user approval…","summary":"Cursor, an AI-assisted code editor, allows writing files inside the workspace without user approval in versions below 1.3.9. Approval is required to edit an existing dotfile but not to create a new one, so when a sensitive file such as .cursor/mcp.json does not yet exist, an attacker can chain an indirect prompt injection to hijack the context, write the settings file, and trigger RCE on the victim without approval.","solution":"Fixed in version 1.3.9.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-54135","publishedAt":"2025-08-05T01:15:41.410Z","cveId":"CVE-2025-54135","cweIds":["CWE-78","CWE-829"],"cvssScore":"8.5","cvssSeverity":"high","severity":"high","attackType":["prompt_injection"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Cursor"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Cursor writes in-workspace files without user approval","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.02105,"epssCheckedAt":"2026-11-04T06:10:15.237Z","kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-04T18:09:29.263Z","patchAvailable":null,"disclosureDate":null,"fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-437","CAPEC-88"],"crossRefCount":1,"attackSophistication":"moderate","impactType":["integrity","confidentiality"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.93,"researchCategory":null,"atlasIds":["AML.T0051"],"fixes":[]}}
